- Allow a few days to give your body time to get used to the heat before you engage in strenuous activity.

- People who are overweight or have other medical conditions should note that they are at high risk for dehydration and heat illness. They should consult their physician before starting any exercise program.

The biggest mistake people make in the heat is not hydrating properly. Follow these guidelines before you work, exercise or play outside:

- Don't use thirst as your guide. If you wait until you are thirsty to hydrate, it is too late.

- Water is good for general hydration. If you are exercising strenuously or for more than an hour, drinks such as Powerade or Gatorade that contain salt and carbohydrates are better.

- Drink 16 ounces to 20 ounces of fluid one hour to two hours before you exercise.

- Take drink breaks every 20 minutes, especially if you are active for longer than one hour.

- Avoid alcohol and caffeine, which cause you to dehydrate more rapidly.

Remember, heat illness can range from heat cramps to heat exhaustion to heat stroke. Heat stroke is dangerous and requires immediate medical attention. Help prevent a more serious problem by knowing the early warning signs:

- Thirst

- Cramps

- Irritability

- Headache

- Weakness

- Dizziness

- Nausea

- Decreased performance

If you experience signs of dehydration, take yourself out of the heat immediately, cool down with a fan and drink fluids. If you do not recover or have a more serious problem, seek medical attention immediately.
